Magnetization studies on superconducting MgB${}_2$ - lower and upper critical fields and critical current density

Amish G. Joshi, C. G. S. Pillai, P. Raj +1

Magnetization studies have been carried out on superconducting MgB${}_2$ (T${}_c$=37K) in the temperature range of 2-50K and in magnetic field up to 5 Tesla. From these measurements, v…
